“To me, I’ve never really gotten the sense that this has been about grabbing every last dollar for Johnny Gaudreau - it’s been more about fit," Seravalli said. Of course, the sway that hefty price tag has remains to be seen. "They’ve put an offer on the table that would not only make Johnny Gaudreau the richest player in Calgary Flames history, but on top of that, one of the select few highest-paid players in the NHL today.” And they’ve put a massive offer on the table," Seravalli said, adding that he believes the latest deal offered to Gaudraeu is north of $10 million per year. There was a significant push from the Calgary Flames in the last 12-24 hours. “These two sides have continued to engage over the last 24 hours or so. NHL insider Frank Seravalli shed some light on where things were at with Gaudreau's negotiations with Calgary, joining Sportsnet 960 on Tuesday to discuss the latest. This means that when the clock hits midnight on Tuesday night, Gaudreau will lose the ability to sign an eight-year deal with Calgary, meaning from that point on, the max option for him - whether in Calgary or anywhere else - will be a seven-year contract.

JOHNNY GAUDREAU'S FUTURE IN CALGARY IN DOUBT AS HE TESTS FREE AGENCYĪs Sportsnet's Elliotte Friedman reported, the Flames star forward has decided to test free agency. For example, the color yellow results from green and red cones being stimulated while the blue cones have no stimulation.NHL market buzz: Latest on Flyers, Senators, what's next for Malkin But it is the overlap of the cones and how the brain integrates the signals sent from them that allows us to see millions of colors. Since the three types of cones are commonly labeled by the color at which they are most sensitive (blue, green and red) you might think other colors are not possible. We have three types of cones. If you look at the graph below, you can see each cone is able to detect a range of colors. Even though each cone is most sensitive to a specific color of light (where the line peaks), they also can detect other colors (shown by the stretch of each curve). Now that we know how these photoreceptor cells work, how do we use them to see different colors? Because the RPE is right next to the discs, it can easily help reload photoreceptor cells and discs with the molecules they need to keep sending signals. This requires the movement of lots of molecules, which they need to replenish to keep working. Rods and cones are similar, but instead of running, they are constantly sending signals. In order to keep muscles in the body working, the runner needs to eat special nutrients or molecules during the race. Think about someone who is running a marathon. While there are many other reasons having the discs close to the RPE is helpful, we will only mention one more. Light can also have damaging effects, so this set up also helps protect your rods and cones from unnecessary damage. This means that your vision is a lot clearer. By having the discs right next to the epithelial cells (retinal pigmented epithelium: RPE) at the back of the eye, parts of the old discs can be carried away by cells in the RPE.Īnother benefit to this layout is that the RPE can absorb scattered light.

Animals that have to see in the dark have many more rods than humans have.Ĭell orientation makes it easier to recycle parts. Other animals have different numbers of each cell type. Many of these are packed into the fovea, a small pit in the back of the eye that helps with the sharpness or detail of images. The human eye only has about 6 million cones.
We have three types of cones: blue, green, and red. The human eye has over 100 million rod cells.Ĭones require a lot more light and they are used to see color.
Rods don't help with color vision, which is why at night, we see everything in a gray scale. We use these for night vision because only a few bits of light (photons) can activate a rod. There are two types of photoreceptors involved in sight: rods and cones. The retina also contains the nerves that tell the brain what the photoreceptors are "seeing." If you think of the eye as a camera, the retina would be the film. This is where the photoreceptors are located. You can see in the drawing on the left that the back of the eye is lined with a thin layer called the retina. Click to enlarge and for more information.
